Postal money order?

I have not been scammed, YET. But I do know some that have. One was via PayPal, the other via USPS. The PayPal victim got nothing, The USPS victim got a Postal Inspector involved and the scammer was charged and convicted of a federal offense, and he did receive more than 1/2 his stolen money returned. I haven't heard if he ever got the rest back. Anyway, for me I like the security of the USPS mo. If the seller doesn't accept USPS, oh well, move on.
